Abstract

The invention provides a power load disaggregation method and system based on current waveform characteristics, related to the technical field of electric power. The power load disaggregation method based on the current waveform characteristics comprises the following steps: obtaining the electrical characteristic parameters of each power equipment in stable operation under each working condition within the monitored power load range, and storing the extracted electrical characteristic parameters into a pre-generated load characteristic database; monitoring the voltage, current and power parameters online at the port of the power load in real time, wherein the power parameters comprise the total active power and reactive power of the power equipment in the monitored power load range; and disaggregating the monitored power load according to the total current parameters at the port of the power load monitored online, and calculating to obtain the existence coefficient of each working state of the electrical equipment in the monitored power load range, so as to effectively realize the power load disaggregation, confirm the power consumption ratio of different power equipment, and further realize the refinement of energy consumption management.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to an electric load decomposition method and system based on current waveform characteristics. Background technique [0002] Non-invasive load monitoring (Non-intrusive Load Monitoring, NILM) or load disaggregation (Load Disaggregation, LD) is a novel power load detail monitoring technology, which can monitor each (category) of the total load The electricity consumption information of electrical equipment realizes (almost) real-time tracking and monitoring, and obtains sub-item electricity consumption information. This technology breaks through the current situation that smart meters can only monitor the total electricity consumption of electric loads. Go deep and refine into the interior of the load. Compared with traditional intrusive monitoring technology, non-intrusive power load monitoring technology has incomparable advantages in investment, deployment and...
